Gregory Korte of USA Today reports, “President Obama called for a more civil debate over the Iran nuclear deal on Friday, telling American Jewish leaders that he shares their concerns about Iran’s threats to Israel but that ensuring a nuclear-free Iran was the most important objective.” While an international deal does not require congressional approval, Obama has sought to reassure Jewish Democrats who have expressed concerns over the negotiations. “As an African American, I understand that history teaches us that man can be very cruel to man, and you have to take threats seriously,” Obama said. “But what history also teaches us is that sometimes the best security is to enter into negotiations with your enemies.”
